'IELLURIAN.

Specification of Letters Patent.

Patented Apr. 9, 1918.

Application filed October 15, 1917. Serial No. 196,725.

T 0 all whom it may concern:

Be it known that I, MORGAN HEATON, a citizen of the United States, residing at Norton, in the county of Norton and State of Kansas, have invented a new and useful Tellurian, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for illustrating approximately but with sufiicient exactness to satisfy the requirements of the lay understanding, the fact that two celestial bodies may move in space, in orbits about a third body, and to illustrate the fact that one of the first specified bodies may move in an orbit around the other, as both of the first specified bodies move around the third body, the structure being of peculiar utility in elucidating the general relations existing between the moon, the earth and the sun.

The present invention aims to provide an exceedingly simple tellurian in which there are practically no parts subject to damage or disorganization due to long extended use.

lVith the above and other objects in view, the invention consists in the novel construction and arrangement of parts hereinafter described, and shown in the accompanying drawings. The drawings show merely a typical embodiment of the invention and it is to be understood that, within the scope of what is claimed, changes falling within the skill of a mechanic may be made without departing from the spirit of the invention.

In the drawings:

Figure 1 is a side elevation;

Fig. 2 is a top plan;

Fig. 3 is a detail perspective view showing the rider.

In carrying out the present invention, there is provided a base or support 1 which may be variously constructed without jeopardizing the utility of the invention. standard :2 is erected on the base 1 and carries at its upper end a body 3 which may be taken to represent the sun. The numeral 4 marks a main orbit member in the form of a ring. The main member 4 may have any desired contour and may be held upon the base 1 by means of staples 5 or otherwise, the main member extending around the body 3 which is carried by the standard 2.

The numeral 6 designates an auxiliary orbit member shown as being held by staples 7 to the base 1. The auxiliary orbit member 6 extends around the main orbit member 4 in spiral form. the convolutions of the spiral being marked by the reference numeral 8. If the apparatus is used to illustrate the general relations between the earth and the moon, there will be 13 of the convolutions 8, and if each of the convolutions 8 be taken to represent twenty-eight days, a close approximation of the length of a year will result. since 13 multiplied by 28 equals 364.

A body 9. representing the earth, is mounted to slide on the main orbit member 4, a body 10. representing the moon, being mounted to slide on the auxiliary orbit member 6. A rider 11 is shown, the same being of V-shape and including arms 12, and an apex 14. The arms 12 terminate in eyes 15 slidably mounted on the main orbit member 4. The apex 14 of the rider 11 has an eye 16 which slides on the auxiliary orbit member 6.

If the body 9 which represents the earth is placed against one of the eyes 15. and if the body 10 which represents the moon is placed against the eye 16, the said bodies may be advanced simultaneously, the body 9 traversirg the main orbit member 4 and the body 10 traversing the auxiliary member 6. The rider 11 is not an absolutely essential element but when employed, it forms an important and satisfactory means for advancing the bodies 9 and 10.

It will be seen that the body 9 will traverse its orbit 4 about the body 3, the body 10 traversing its orbit 6 with respect to the body 3 and also moving in an orbit around the body 9, the structure being useful to illustrate, with sufiicient exactness, the general relations which exist between the earth, the moon and the sun.

Having thus described the invention, What is claimed is:

1. A tellurian embodying main and auxiliary orbit members fixed with respect to each other, the auxiliary orbit member be ing disposed in spiral form around the main orbit member; bodies mounted to slide on the respective orbit members; a third body around which the orbit members extend; and means for holding the third body in place with respect to the orbit members.

2. A tellurian constructed as described in claim 1 and further characterized by the as my own, I have hereto aiiixed my'signaprovision of a rider mounted to slide on herein the presence of two Witnesses.
